Using futures with boost::asio

Question

Does anyone have a good pointer to examples which use futures from the Boost thread library with Boost ASIO? I have an existing asynchronous library which uses callback function

Answer 1

Can you please look at this example:

http://www.boost.org/doc/libs/1_61_0/doc/html/boost_asio/example/cpp11/futures/daytime_client.cpp

It shows how to use std::future with boost asio.

The key point is to include file use_future.hpp:

#include 

Then you can write code like that:

std::future my_future =
    my_socket.async_read_some(my_buffer, boost::asio::use_future);

If you need to use boost::future then I'd suggest to implement another variant, similar to boost::asio::use_future.
The file use_future.hpp is a good example for that.
